Definitions
- the present invention relates to a technique for suppressing electromagnetic waves leaking through a power distribution circuit provided on a printed wiring board or a semiconductor package and preventing deterioration of a signal waveform excited by a high-speed digital circuit. Connected between power distribution circuits, the characteristic impedance of the power distribution circuit side as viewed from the high-speed digital circuit is reduced to a low impedance over a wide frequency band to suppress leakage electromagnetic waves and to be excited by the high-speed digital circuit
- the present invention relates to a stripline element suitable for preventing signal waveform deterioration, a circuit board using the element, a semiconductor package, and a method of forming a stripline element.
- the power distribution circuit is a circuit including a power supply circuit and a power distribution wiring for supplying power supplied from the power supply circuit to another circuit. The leaked electromagnetic waves propagate to the power supply circuit via the power distribution wiring and other circuits, and cause a failure in the circuit supplied from the power supply circuit.
- part of the leaked electromagnetic wave propagating through the power distribution wiring passes through the power supply circuit and propagates to the commercial AC power supply line, and the commercial AC power supply line plays the role of an antenna and radiates high levels of unnecessary electromagnetic waves into the air.
- the leaked electromagnetic wave propagating in the power distribution wiring repeats reflection in the middle of the power distribution wiring, and a part of it propagates to the signal wiring to deteriorate the signal waveform.
- a drastic measure to solve the above problems is to prevent electromagnetic waves generated by circuit operation (for example, switching operation by switching elements) from leaking to the power distribution wiring as shown in Fig. 1. .
- the impedance at high frequencies when the power distribution circuit is viewed from the circuit that generates the electromagnetic waves must be very low for all the frequency bands included in the electromagnetic waves.
- the impedance of the power distribution circuit viewed from the transistor is as close as possible to zero, the electromagnetic wave excited by the transistor will not be reflected at the entrance of the power distribution wiring and will not enter the power distribution circuit.
- Capacitors have been used so far to reduce the impedance of power distribution wiring. Capacitors have a long history as components used in electrical and electronic equipment, and various types of capacitors have been put to practical use. At present, ceramic capacitors with a multilayer structure of ceramic materials on which metal thin films are deposited, and conductive polymers with a porous molded body of metal such as tantalum and aluminum having a valve action as an anode and an oxide film as a dielectric are used as conductive polymers. A solid electrolytic capacitor having a structure in which is used as a solid electrolyte has been developed.
- a solid electrolytic capacitor As a solid electrolytic capacitor, a solid electrolytic capacitor having, as a solid electrolyte, polypyrrole or an alkyl-substituted product thereof on a dielectric oxide film (for example, see Patent Document Alternatively, a solid electrolytic capacitor in which polyaniline is formed as a solid electrolyte on a dielectric oxide film and a method for manufacturing the same (for example, see Patent Document 2) are known. These capacitors use a conductive polymer with a conductivity that is at least two orders of magnitude higher than the previous ones, so their equivalent series resistance is low, and even if they have the same capacitance, The effect was obtained up to the high frequency range of two digits or more.
- FIG. 2 is a cross-sectional view showing the configuration of the surface-mount type noise filter including a meandering conductor and a ground conductor sandwiched between ceramic dielectric sheets.
- the conventional surface mount filter has a configuration in which a first dielectric sheet 110, a second dielectric sheet 120, and a third dielectric sheet 130 are laminated, No.
- a first inner conductor 111 At the interface between the dielectric sheet 110 and the second dielectric sheet 120, a first inner conductor 111, a meandering conductor 115, and a second inner conductor 112 used for signal transmission are arranged.
- a ground conductor 125 is formed at the interface between the second dielectric sheet 120 and the third dielectric sheet 130 so as to face the meandering conductor 115.
- One end of the first inner conductor 1 1 1 is connected to the first signal electrode 15 1 and the second inner conductor 1
- One end of 1 2 is connected to the second signal electrode 15 2, and the meandering conductor 1 15 is connected between the other end of both the first inner conductor 1 1 1 and the second inner conductor 1 1 2 .
- the capacitance formed as a distributed constant is constituted by the ground conductor 125, the meandering conductor 115, and the dielectric sheet laminated between them, and Since it is difficult to reduce the impedance value efficiently in the high-frequency region exceeding 10 MHz using only the capacitance, it is possible to combine the capacitance and the series inductance by using a part of the inner conductor as a meandering conductor. To increase the signal attenuation effect.
- the multilayer printed circuit board disclosed in Patent Document 4 has the following configuration.
- Ground layers are laminated on the upper and lower sides of the power supply layer on which the power supply wiring is provided via a first insulating material layer, respectively, and signal wirings are disposed on one or both sides of these upper and lower sides via a second insulating material layer. It is characterized in that the provided signal layers are laminated.
- the transmission line type component disclosed in Patent Document 5 is made of a conductive material having a larger diameter than the inner conductor via a high dielectric constant insulating material so as to cover the surface of the inner conductor made of a conductive material.
- a coaxial line with extremely low characteristic impedance is formed by arranging a cylindrical outer conductor coaxially. This is inserted in series between the power supply line of the printed circuit board and the power supply port of the high-speed and high-frequency circuit element such as LSI, so that each high-speed and high-frequency circuit element mounted on the printed circuit board is DC power in the same state as when an independent low impedance power source is provided.
- Power can be supplied, and high-speed, high-frequency power generated from high-frequency circuit elements by high-speed switching operation causes dielectric loss inside the transmission line-type component, power coupling between power supply lines and signal lines, and power supply to printed circuit boards It is said that it is possible to suppress the outflow of high-frequency power supply current from the wire to the power supply cable inside the device.
